This listing is for ONE full-wave rectifier 5V4G vacuum tube in the ST shape. It has a black base, black plates, and one bottom or top getter. We have various vintage USA brands, presently GE, Sylvania, Tung-Sol, Crosley, and RCA. Send a message if you prefer a particular make or label, otherwise we'll just grab the closest one on the shelf. 5V4GA, which is straight-walled, is available in a separate listing.
Your tube has been fully tested on an Amplitrex AT1000 with like new, tNOS results. Here's what that means: to qualify for this listing, the forward voltage in the two sections must be balanced within 10% of each other, and that voltage must be between 12 and 18 Volts for both sections. Unbalanced and used-testing tubes are available in a separate listing at a significant discount.
The Amplitrex tests for gas, shorts, and leakage as well. The tube you receive is guaranteed against failure for 60 days after purchase.
